IMPROVEMENT IN DEVICES FOR RAISING AND LOWERING CATTLE-RACKS 0NPLATFORM-SCALES.

Specification forming part of Letters Patent No. 165,217, dated July 6,1875; application filed May 15, 1875.

To all whom it may concern Be it known that I, PRESTON G. Deen- STADER,of Lyndon, in the county of Whitesides and State of Illinois, haveinvented a new and Improved Device for Raising and Lowering Cattle-Rackson PlatformSc-ales, of which the following is a specification Theinvention will'first be described in connection with drawing, and thenpointed out in the claim.

In the accompanying drawing, Figure l is a side view of the deviceattached to one corner of the cattle-rack. Fig. 2 is an edge view of thesame. Fig. 3 is a view looking upward from the line a :10 of Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the cattle-rack. B is a plate, which is securely fastenedto each corner of the rack. On this plate is a pin, (1, cast with theplate, or rigidly attached thereto, which extends below the lower edgeof the plate. I) is a slide, which is dovetailed (by means of cleats orribs E E) to the plate. At the lower end of this slide is an axle, F, onwhich is wheel G. H is a rib on the slide. I is a but ton attached tothe plate by which the slide is locked when at its lowest position. J isa cap on the upper end of the slide, which acts as a stop to prevent theslide and wheel from descending too far.

When the rack is lowered on the scales the pins 0 enter holes in thescales, the buttons being removed from the ribs of the slides. When therack rests in this position on the scales, the wheels hang above thescales. When the rack is raised to the position seen in thedrawing, thelocking-buttons are made to engage with the ends of the ribs, and theweight of the rack rests on the wheels, and the rack may be rolled off,as may be desired.

Ido not confine myself to this particular
